IGN Marvel's Agents of SHIELD: "Chaos Theory" Review

IGN:
Once again, SHIELD moved very quickly this week, as the revelation that Andrew is Lash resulted in an immediate confrontation between the team and their friend turned murderous Inhuman.

I must say, I was a bit disappointed to find out Andrew/Lash was simply driven by a vampiric sort of compulsion to kill other Inhumans, rather than any bigger or more complicated purpose, as seemed to be the case earlier this season. Certainly, when he killed Dwight Frye a few episodes back and said, "I'm not merciful, I'm necessary," it felt like some bigger agenda was at work than what was revealed this week.
